GUN-SIGHT TELESCOPE.

SPECIFICATION forming Of Letters Patent NO. 722,910, dated March 17, 1903. Application filed December 8, 1902. Serial No. 134,339. (ll'o model) ToaZZ whom. it may concern.-

Be it known that I, GEORGE N. SAEGMUL LEE, a citizen of the United States, residing at iVashingtonJn the District of Columbia,have invented certain new and useful Improvements in Gun-Sight Telescopes, of which the following is a specification, reference being mitting its use in the recoil of a gun withoutinjury to a person making the observation therethrough.

A further object of the invention is. to

mount a shield or protector so that it may reciprocate in the recoil'of a gun and beimmediately restored'to its initial and proper position;

Other and further objects and advantages of the invention will be hereinafter set forth,

and the novel features thereof defined by the appended claims.

In the drawings, Figure 1 is an elevation showing the telescope applied to a .piece of ordnance; Fig. 2, section of the telescope;'Fig. 3, a side elevation of a biconvex eye-lens, and Fig. 4 a similar view of an achromatic lens.

Like letters of reference refer to like parts in the several figures of the drawings.

The invention is intendedfor us'ein an y desired position, but is illustrated in Fig. 1 as applied to a piece of ordnance (indicated at A) to which it is particularly applicable. In this figure a bracket A is'dispose'd at one side of the carriage A of the gun and the telescope B supported therein by any suitable form of standard A and securing device A The telescope B is provided with the usual c'asing B, which maybe formed of telescopic sections or otherwise as found desirable, and

is provided at-its outer end with a piano-com,

vex field-lens B 'and between its ends with suitable lenses B and B of a similar characan enlarged longitudinal ter forerecting the. image and conveying the rays of light, as indicated by diagramin Fig. 2. At the opposite end of the instrument from the field-lens an eye-lens B is provided and is of mnchlarger size than that ordinarily used in telescopes of this character, the objectthereof being to project the image at a point removed from the lens, as indicated at C, while extending from the eye-lens to this focusing-point C is a protector or shield C of any desired character, preferably formed of elasticmaterial, so as to permit a vibration of the-instrument during the recoil from the piece of ordnance fired without injury to the observer. This eye-lens B is shown by detail.

in Fig. 3 as a biconvex lens having its faces of difierent radii, according to the length of the eyepiece used to project the image to the open end of the eyepiece. The invention, however, is not confined to this particular construction of eye-lenshor to any specific arrangement of the'other lenses used in the instrument, as an achromatic lens (shown at B in Fig. 4) may be used to correct spherical and achromatic aberration.

For the purpose of permitting a vibration ofthe protector or shield, thus maintaining 1 ,it in proper relation to theeye of the operator during the firing of a gun, this shield is mounted on a sliding frame or ring 0 normally held against a stop 0 at the end of the instrument by means of a coiled spring C extending from the frame 0 to a fixed shoul-- der 0 upon the casing B,- thus normally hold-- ing the shield in correct position, while the recoil'of thegun produces alongitudinal vi bration in the instrument, causing the shield to compress the spring and travel in a path through which the light-rays travel in substantially parallel planes, thus not affecting the relation of the position of the operator to the other parts of the instrument during thisv momentary vibration. I

t The invention may be applied to any desired character of telescope and also to any piece of, ordnance or similar apparatus in which it is desired. to project the image at a point beyond the eye lens-and at the open end of an extended protector, thus permitting the vibration of the parts without injury thereto or to the operator using the same. v Having described my invention and set forth its merits, what I claim, and desire w I secure by Letters Patent, is

1. In a telescepe, casing pi'ovide'l. with field and meeting lenses fixed eye-lens mounted within said casing, and a yieldinglynwunted px'ot-etor movable relmive to said I eye-lens; substantially as specified. l

2. In a telescope, a relatively fixed casing l carrying field and erecting lenses, an extended yieldingly-movable protectoixat ue end of I said casing, and an enlarged eye-lens fixedly (llEPOSGd ix; said casing approximately at; the

base said pmteetor and adapted-t0 project an image to the outer edge thereof; substaxr tially 2m spaciied.

In testimony whereef K affix my signabure in presence of two witnesses.
